Effect of Cdx2 siRNA on confluence-dependent CD26 expression in HCT-15 cells. The effect of Cdx2 siRNA on the confluence-dependent CD26 protein expression in HCT-15 was evaluated following transient transfection (when cells were at 90% confluence) of control siRNA (left) or Cdx2 siRNA (right) as described in Materials and Methods. CD26 and Cdx2 protein expression were analyzed by Western blotting and quantified by densitometric analysis. Data shown are representative of three independent experiments.
